webSocket 案例 使用spring4.0.0

因爲最近一個項目中要使用常練接的問題 要求是使用spring中的websocket 但是 親們 你們知道嗎？ spring中websocket是一個深坑呀~ 太坑了

所以整理了一下 關於spring-websocket的相關問題 防止以後忘記了~~~~~~~ 啊哈哈 

步驟：

        1、將websocket-config注入到spring中

        2、將websocket配置的鏈接注入到websocket-config中

        3、編寫相關的業務邏輯

WebSocket-Configer

package com.keepalive.controller;

import org.springframework.context.annotation.Bean;

import org.springframework.web.socket.server.standard.ServerEndpointExporter;

import org.springframework.web.socket.server.standard.ServerEndpointRegistration;

import com.gateguard.keepalive.service.CaseEndPointService;

public class WebSocketConfiger

{

    @Bean

    public ServerEndpointExporter endpointExporter(){

        return new ServerEndpointExporter();

    }

    /**

     * 綁定webSocket的鏈接和實現類

     * @return

     */

    @Bean

    public ServerEndpointRegistration caseCount()

    {

        System.out.println("caseCount");

        return new ServerEndpointRegistration("/casecount", CaseCountEndPoint.class);

    }

    /**

     * 綁定webSocket的鏈接 主要是單例模式 

     * @return

     */

    @Bean

    public ServerEndpointRegistration caseCountSingle()

    {

        System.out.println("caseCountSingle");

        return new ServerEndpointRegistration("/casecountsingle", new CaseCountEndPoint(caseEndPointService()));

    }

    @Bean

    public CaseEndPointService caseEndPointService() {

        return new CaseEndPointService();

    }

}

spring-configer

<beans:bean id="websocket" class="com.keepalive.controller.WebSocketConfiger">

CaseCountEndPoint

package com.keepalive.controller;

import java.io.IOException;

import javax.websocket.Endpoint;

import javax.websocket.EndpointConfig;

import javax.websocket.MessageHandler;

import javax.websocket.Session;

import org.springframework.beans.factory.annotation.Autowired;

import com.gateguard.keepalive.service.CaseEndPointService;

public class CaseCountEndPoint extends Endpoint 

{

    private final CaseEndPointService caseEndPointService;//這裏 final必須添加

    @Autowired

    public CaseCountEndPoint(CaseEndPointService caseEndPointService) {

        this.caseEndPointService = caseEndPointService;

    }

    @Override

    public void onOpen(final Session session, EndpointConfig endpointConfig) {

        System.out.println("進入 webSocket onOpen");

        session.addMessageHandler(new MessageHandler.Whole<String>() {

            @Override

            public void onMessage(String message) {

                System.out.println("接受信息"+message);

                try {

                    session.getBasicRemote().sendText(String.valueOf(caseEndPointService.getCount()));

                } catch (IOException e) {

                    e.printStackTrace();

                }

            }

        });

    }

}

CaseEndPointService

package com.keepalive.service;

public class CaseEndPointService 

{

    public double getCount()

    {

       return Math.random();

    }

}

jsp：

使用lib文件：spring-websocket-4.0.0.RELEASE.jar
